SPI as slave from user space in linux

[kartheek]

Hi Team,

I'm using a board with an imx8m plus CPU called a humming board pulse (controller). My controller will be used as an SPI slave. Tell me about any Linux user space APIs that I may use to use my controller as a slave, please.

Thanks & Regards,

Kartheek

Are you using the NXP reference board? Which version BSP are you using? How do the controller connect to the i.MX8MP board?
